  1. What was Mariner 10? Mariner 10 was the first spacecraft sent to the planet Mercury; the first mission to explore two planets (Mercury and Venus) during a single mission; the first to return to its primary destination for another look; and the first to use a gravity assist to change its flight path.

  2. Nov 5, 2018 · In 1969, NASA approved a plan to send a spacecraft to Mercury, using Venus for a gravity assist. The mission, first known as Mariner Venus Mercury, was later renamed Mariner 10 and managed by the Jet Propulsion Laboratory in Pasadena, California.

    During its flyby of Venus, Mariner 10 discovered evidence of rotating clouds and a very weak magnetic field. Using a near-ultraviolet filter, it photographed Venus's chevron clouds and performed other atmospheric studies. The spacecraft flew past Mercury three times.

  4. Feb 5, 2019 · Mariner 10 contributed significantly to our understanding of Venus during its fly-by. It confirmed that Venus lacks an appreciable magnetic field to deflect the solar wind, but its considerable atmosphere and ionosphere act to modify the stream of particles emanating from the Sun.

  5. A unique opportunity presented itself in 1973 to send a spacecraft to visit both Venus and Mercury in a single mission. Using gravity assist, a technique theorized for decades but never used before, under favorable conditions a spacecraft sent to…

  6. As it sped away from Venus, NASA's Mariner 10 spacecraft captured this seemingly peaceful view of a planet the size of Earth, wrapped in a dense, global cloud layer. But, contrary to its serene appearance, the clouded globe of Venus is a world of intense heat, crushing atmospheric pressure and clouds of corrosive acid.
